HYDROTHERMAL SYNTHESIS OF NANO-ZEOLITE F FROM KAOLIN TAILINGS
Kaolin tailings, from Amazon Region (Brazil), were employed as starting material to obtain zeolite F-type material under low-temperature hydrothermal synthesis in alkali solution with KOH. The effects of K/Al ratios, temperature and crystallization time on the crystalline products were investigated. The materials were characterized using X-ray diffractometry, scanning electron microscopy and transmission electron microscopy. The results showed that the kaolin tailings were successfully transformed into nano-zeolite F, with a high degree of crystallinity and morphology in nanorods.
